Demographics plotting issues and documentation

[rickecon]

Since updating the mortality rates rho object to allow for time varying mortality rates in PR #73, the plotting functions in demographics.py functions get_fert(), get_mort(), and get_imm_rates() have stopped working. This has caused the documentation to stop building because much of the executable code in the calibration: demographics section depends on those plotting functions. We need to fix those plotting functions.

@rickecon I tested this with my ogusa-dev environment, which has

(ogusa-dev) jason.debacker@JDEBACKER-7 OG-USA % python --version
Python 3.11.6
(ogusa-dev) jason.debacker@JDEBACKER-7 OG-USA % conda list matplotlib
# packages in environment at /Users/jason.debacker/anaconda3/envs/ogusa-dev:
#
# Name                    Version                   Build  Channel
matplotlib                3.8.0           py311h6eed73b_2    conda-forge
matplotlib-base           3.8.0           py311hd316c10_2    conda-forge
matplotlib-inline         0.1.6                    pypi_0    pypi

And I am able to successfully produce plots to the default directory. Code to reproduce:

import ogusa.demographics as demog
demog.get_fert(graph=True)
demog.get_mort(graph=True)
demog.get_imm_rates(graph=True)

If you are having issues, can you share the version of Python and Matplotlib being used (or other packages you think are relevant to the error)?

We moved the demographics module to OG-Core (PR #86 removes it from OG-USA) and these issues have been solved.
